Proteins Flashcards
assist your body in creating new cells
and repairing existing ones.
● provide structural support, biochemical
catalysts, hormones, enzymes, building
blocks, and trigger cellular death.
Proteins
What is the monomer of
PROTEINS?
Amino Acid
Greek word “proteios” meaning
First place
Proteins are important in the structure
of the cells; they serve as
○ Gene activators
○ Membrane receptors
○ Transporters
○ Clotting factors, etc.
SEVEN MAJOR
CLASSES OF PROTEINS
- Structural Protein
- Contractile Protein
- Storage Protein
- Defensive Protein
- Transport Protein
- Signal Protein
- Enzymes
● Found in the hair of mammals
● Fiber that makes up the tendons and
ligaments
Keratin, collagen, and elastin are
examples of structural proteins.
Structural Protein
● Proteins that provide muscular
movement
Contractile Protein
● Such as ovalbumin, the main substance
of egg white
Storage Protein
● includes antibodies that promote
protection against foreign bodies
Defensive Protein
● includes antibodies that promote
protection against foreign bodies
Defensive Protein
includes hemoglobin, the
iron-containing protein in the blood that
transports oxygen from the lungs to the
other parts of the body.
Transport Protein
Such as hormones which help
coordinate body activities
Signal Protein
Serves as the chemical catalyst that
changes the rate of chemical reactions
Enzymes
Amino acids are linked by a peptide
bond also called the
Amide Bond
